Documentary filmmaker Michael Moore appeared on "The Colbert Report" Monday night, where he chatted with host Stephen Colbert about the importance of unions.

"Comrade, the tractor does not belong to all of us," Colbert admonished him, arguing against the necessity of unions and collective bargaining.

"The street and the bridge and the school and the library, and this country does belong to all of us," Moore retorted.
